I got a new Mac Pro and I am using my 30 inch cinema display.  It has been flickering grey sometimes and then will stay grey and lock up my computer and I have to reboot... this is very annoying..help.  I have reset the pram and that seems to help for a bit but then it starts up again...and please don't tell me to check for software updates:)

Mac Pro, OS X Mountain Lion (10.8.2)
